Jada began dating Will in 1995 when he was still technically married to Sheree.
Union, who recently appeared on Red Table Talk - Pinkett Smith's new offering on Facebook Watch - said the sky's the limit now that she and the Girls Trip actress are on the same page. "And here's the one thing I will say in hindsight - because I did not understand marriage, I didn't understand divorce".
Pinkett Smith confessed to being inconsiderate and insensitive to Zampino and Smith during the end of their marriage and to being focused on immediately developing a co-parenting arrangement, even though it was uncomfortable for the estranged couple at the time.
"You think?!?!" Sheree snapped back.
Pinkett Smith and the Suicide Squad star first began dating when he was separated from his first wife, but not yet divorced from her.
"Trey comes home and I said, 'How did you like Miss Jada?'" Zampino recalled to a tearful Pinkett Smith.
The first episode of Jada Pinkett Smith's new talk show, "Red Table Talk", premiered on Facebook earlier this week - and Pinkett Smith dove into the difficulties of motherhood by sharing the stage with her husband's first wife, Sheree Fletcher. "It was like, 'Okay, well, you did that, and that's done, '" she explained.
Jada told Extra last week that she felt her chat on the show with Union was 'really touching, ' admitting they hadn't 'been on the best of terms for 17 years'.
"And that's what we talk about on her show - how we got over ourselves, how we both evolved - no feud, just a lot of silence - to come together and create something really handsome with a lot of healing".
"Well, I want you to know, that Will Smith let me have it", Pinkett Smith said. "And thank you for that".
"And he's got a great mother", Jada responded.
Both women expressed gratitude to each other for helping raise Trey, who is now a DJ, performing under the name DJ Ace.
